- Carbon Cycle - Sections concisely summarize the history of the element and its presence on earth, from its discovery in 1594 to topics such as carbon dioxide, carbon monoxide, fossil fuels, and carbon credits and sequestration.
- Carbon Dioxide Information Analysis Center (CDIAC) - Global-change data and information analysis for the US Department of Energy (DOE). Atmospheric concentrations of carbon dioxide and other radiatively active gases; role of the terrestrial biosphere and oceans in biogeochemical cycles of greenhouse gases; emissions of carbon dioxide; long-term climate trends; effects of elevated carbon dioxide on vegetation; vulnerability of coastal areas to rising sea level.
- Fluxnet Canada - A Canadian research network, based on eddy covariance flux measurements, that studies the effects of climate and disturbance on carbon cycling processes in forest and peatland ecosystems.
- Global Carbon Project - Scientific partnership that aims to develop a complete picture of the global carbon cycle, including both its biophysical and human dimensions together with the interactions and feedbacks between them. A project of the Earth System Science Partnership of the International Geosphere Biosphere Programme (IGBP), World Climate Research Programme (WCRP), and the International Human Dimensions Programme (IHDP)
- Mystery of the Missing Carbon - Discusses the BOREAS research program, which investigated the "missing carbon" problem in global carbon cycle studies.
- The BOREAS Project - The Boreal Ecosystem-Atmosphere Study (BOREAS) is a large-scale international interdisciplinary experiment in the northern boreal forests of Canada. Its goal was to improve our understanding of the boreal forests - how they interact with the atmosphere, how much CO2 they can store, and how climate change will affect them.
- United States Trace Gas Network - The TRAGNET network is meant to accomplish the following two goals: 1. Document contemporary fluxes of CO2, CH4 and N2O between regionally important ecosystems and the atmosphere and 2. Determine the factors controlling these fluxes and improve our ability to predict future fluxes in response to ecosystem and climate change.
- US Carbon Cycle Science Program - An interagency partnership to provide critical unbiased scientific information on the fate of carbon dioxide in the environment to contribute to the ongoing public dialogue.
